Zillow's results beat expectations, but the guidance left something to be desired. The real-estate company now sees fourth-quarter revenue of $30 million to $31 million, while analysts were looking for $32.5 million. Management blamed the shortfall on the loss of Foreclose.com, one of its big advertisers. Z plunges 18 percent before the bell on my tradeMONSTER platform.
